Constant Temperature and Humidity Chamber

Constant Temperature and Humidity Chamber

HA Measuring by JINGYAO INSTRUMENT equips labs to build, test, fill and pack e-cigs, plus car, climate, sports, battery and furniture tests and charging aging cabinets.

Equipment Usage


Our high-performance Constant Temperature and Humidity Test Chamber is engineered to provide precise environmental simulation for rigorous quality control and reliability testing. Built to meet the stringent requirements of research, development, and production across a wide range of industries—including electronics, batteries, automotive, materials science, and pharmaceuticals—this equipment helps ensure your products can withstand extreme operating conditions.

Key Features

  • Precision Control: Achieve highly accurate test environments with a temperature resolution of ±0.01°C and a humidity resolution of ±0.1% R.H.

  • Broad Environmental Range: Simulate a wide variety of conditions, from -40°C to +150°C and 20% to 98% R.H.

  • Consistent Performance: Designed for stability, with controlled temperature fluctuation (±1°C) and uniformity (±2°C) to deliver reliable results throughout the entire inner chamber.

  • Rapid Cycling: Optimized heating and cooling rates support efficient testing, enabling non-linear, no-load transitions between ambient and extreme temperatures.

  • Robust Compliance: Our chambers fully comply with international and domestic testing standards, including IEC 68-2-1/2/3/30 and various GB/T standards—helping ensure your testing processes meet globally recognized quality benchmarks.

Why Choose Our Chambers?

Whether you conduct low-temperature endurance tests, high-temperature operation tests, or constant/alternating damp heat tests, our chambers provide a stable and repeatable environment required for valid certifications and quality assurance. By simulating real-world environmental stressors, we help you reduce product failure rates, accelerate R&D cycles, and support compliance with industry-specific standards.
